Space Shuttle Mission STS-134 Final Flight of Endeavour overview

4. STS-134 Mission Overview During the 14-day mission, Endeavour will deliver the Alpha Magnetic Spectrometer (AMS) and spare parts including two S-band communications antennas, a high-pressure gas tank, additional spare parts for Dextre and micrometeoroid debris shields. This will be the 36th shuttle mission to the International Space Station.

14. Docking Overview:

15. Payload Overview:

16. Payload: Endeavour will deliver to the International Space Station the Alpha Magnetic Spectrometer-2 (AMS). AMS, a particle physics detector, is designed to search for various types of unusual matter by measuring cosmic rays. Its experiments are designed to help researchers study the formation of the universe and search for evidence of dark matter, strange matter and antimatter.

17. AMS-2 Overview:

18. Payload: Endeavour also will fly the “Expedite the Processing of Experiment to Space Station” (Express) Logistics Carrier 3 (ELC3), a platform that carries spare parts that will sustain space station operations once the shuttles are retired from service.

19. ELC3 Overview:

20. EVA 1 - Flight Day 5: Feustel and Chamitoff will retrieve two experiments and install a new package of experiments on ELC2, which is already on the station. They will install jumpers between segments on the left-side truss, or backbone of the station, for ammonia refills; vent nitrogen from an ammonia servicer; and install an external wireless communication antenna on the Destiny laboratory that will provide wireless communication to the Express Logistics Carriers mounted on the station’s truss. Spacewalks: EVA 2 - Flight Day 7: Feustel and Fincke will refill radiators with ammonia. They also will complete venting the early ammonia system, lubricate a left-side solar joint and parts of Dextre, a two-armed space station robot capable of handling delicate assembly tasks currently performed by spacewalkers.

21. EVA 3 - Flight Day 9: Feustel and Fincke will install a grapple, or handle for the robotic arm on the station to grab, on the Zarya module to support robotic operations based from the Russian segment. They also will install additional cables to provide backup power to the Russian portion of the space station. Spacewalks: EVA 4 - Flight Day 11: Fincke and Chamitoff will stow the shuttle’s 50-foot boom on the right-side truss on a permanent stowage fixture, retrieve the grapple from the station's left-side truss and use it as a replacement for the grapple currently on the boom. They then will release restraints from one of the arms on Dextre and replace thermal insulation on one of the spare gas tanks for the Quest airlock.
